Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Details on results:
There was 100% mortality in the lowest test group
Under flow test condition concentrations are nominal, but the toxicant is continuously added to water stream to keep the actual concentrations

Description of key information

Long term toxicity work and studies on early life stage fish show similar variation between studies.  

The most severe data is used for classification, suggesting long-term LC50 in range 0.01 - 0.1 mg/l, confirming Aquatic Chronic 2 (considering rapid biodegradation)

Key value for chemical safety assessment

Fresh water fish

Fresh water fish
Dose descriptor:
Note that LC50 cited in data.
Effect concentration:
